4.6.8. SDI Video Input/Output Ports
The Intel Stratix 10 GX FPGA development board includes a SDI port, which consists
of a M23428G-33 cable driver and a M23544G-14 cable equalizer. The PHY devices
from Macom interface to single-ended HDBNC connectors.
The cable driver supports operation from 125 Mbps to 11.88 Gbps. Control signals are
allowed for SD and HD modes selections, as well as device enable. The device can be
clocked by the 148.5 MHz voltage-controlled crystal oscillator (VCXO) and matched to
incoming signals within 50 ppm using the UP and DN voltage control lines to the
VCXO.

The cable equalizer supports operation at 270 Mbit SD, 1.5 Gbit HD and 3.0, 6.0, and
11.88 Gbit dual-link HD modes. Control signals are allowed for bypassing or disabling
the device, as well as a carrier detect or auto-mute signal interface.
